The Layser cave is an important archaeological site of Washington. This area was inhabited for 7,000 years, the caves were used during the first half of this period, the caves were abandoned 3,500 years ago when an eruption of Mount St. Helens forced the people to leave. The eruption buried native settlements with a thick layer of pumice. But what was a disaster for the ancient people is now a stroke of luck for modern archaeologists.
